Perimeter = 2 width + 2 length
= 2 (x-5) + 2 (9x+4)
= 2x-10+18x+8
= 20x-2
the area of the rectangle = width * length
= (x-5) * (9x+4)
= 9x^2 - 41x - 20

Step-by-step explanation:

Expected number of days until prisoner reaches freedom=E(x)=?

E(x)=x*p(x)

Where x is the number of days and p(x) is the probability associated with them.

X    1    2    3

P(x) 0.5 0.3 0.2

E(x)=1*0.5+2*0.3+3*0.2
